Answer:
cos210=cos(180+30)=−cos30=−√32 . sin210=sin(180+30)=−sin30=−12 . 3(cos210+isin210) =3(−√32)+3i(−12). −(32)√3−(32)i. My favourite way of seeing that sin30=12 and cos30=√32 is ...
Step-by-step explanation:
But that's what I say personally
Answer:
3150
Step-by-step explanation:
So basically 5 x 1/4 would equal 1 1/4 ( One, One Fourth )
Since complementary angles add up to 90 degrees, we simple take
and simplify it to
°
35 I believe is the answer
